Collectibles and completion
Optional discoveries, useful collections and completion goals in Metal Gear Solid 2.
Spoiler notice: This guide discusses story progression or late-game content.
Sons of Liberty campaign. Shared mechanics documented in the Master Collection manual; original PS2 controls and collection bindings can differ.
Dog tags
Hold up guards and make them surrender their tags. Tags are associated with difficulty and chapter, so track Tanker and Plant progress separately.
Gadgets and weapons
Equipment access changes with story progress. Check your inventory before following a route that assumes a sensor, weapon or security level you have not yet received.
Bonus equipment
Tag rewards are longer-term unlock goals. Consult the reward requirements for your edition and avoid confusing original-game unlocks with Master Collection achievements.
Use the edition note above when comparing a checklist with another release. Story completion, collecting and platform achievements are separate goals.
